Single Implementation to Parse Similarly Structured XML files

Question

Is there a way to have a single implementation in Java that can read/parse an XML file with normal elements and another with prefixed elements? Both versions have the same structure.

i.e.

XML-1

<root>
  <element attribute="value">
  </element>
</root>

XML-2

<pre:root xmlns:pre="someURL">
  <pre:element attribute="value">
  </pre:element>
</pre:root>

Answer 1

Using DOM, invoke the following:

DocumentBuilderFactory.setNamespaceAware(true);

Then use the wildcard when searching for tags:

Document.getElementsByTagNameNS("*","elementName");

Answer 2

This should be possible. When parsing using DOM/SAX/StAX you will need to account for the fact that sometimes the unqualified element name will correspond to what the parser considers the "qualified name" and sometimes it will correspond to the "local name".
